No heating downstairs

Hi. Just moved into a home with Tado. 2x wired thermostat, one bridge, one extension. Boiler is potterton, not combi we have a tank.

When we moved in no internet bridge. Tado gave us a workaround. Heating upstairs was fine intermittent downstairs.

Bought a new bridge, all installed and connected. App can control all zones but no heating downstairs even though thermostat and app are set for it to be on. Please help


  • I’m guessing your issue is due to the CH relay in the extension kit being permanently open. This relay is normally operated when using a wireless thermostat, but as you are using a wired thermostat you may need the relay closed for the downstairs thermostat to work. This is only a guess and it depends on how your heating system is wired.
